Complete atomic migration to structured data architecture
All checks were successful
Build and Release / build-and-release (push) Successful in 1m7s

Implements clean structured data collection eliminating all string metric
parsing bugs. Collectors now populate AgentData directly with type-safe
field access.

Key improvements:
- Mount points preserved correctly (/ and /boot instead of root/boot)
- Tmpfs discovery added to memory collector
- Temperature data flows as typed f32 fields
- Zero string parsing overhead
- Complete removal of MetricCollectionManager bridge
- Direct ZMQ transmission of structured JSON

All functionality maintained: service tracking, notifications, status
evaluation, and multi-host monitoring.
